Which would scientists predict might happen due to solar flares?(1 point)

Scientists predict that due to solar flares, the following may happen:

1. **High-frequency radio waves used for radio communication will be blocked.**
2. **Radio navigation systems and global positioning systems will be inaccurate.**
3. **Electrical systems in satellites will fail.**
4. **Power grid operations may go down.**

All of these responses are valid consequences of solar flares, as they can disrupt communication, navigation, and power systems due to the increased electromagnetic activity.
